P1200 grade is ideal for removing runs and leveling minor dust nibs as well as smoothing mismatched orange peel from topcoat finishes before repainting or buffing. This grade range is suitable for all metals and all automotive paints. Our 3M™ Hookit™ Film Disc 260L combines durable film backing with fast-cutting, long-lasting aluminum oxide mineral abrasive. Aluminum oxide is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness, and strength, it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in metalworking, including ferrous alloys. The Hookit™ hook-and-loop feature makes disc attachment, removal, and re-attachment clean and easy, and facilitates use and re-use of the disc for the extent of the abrasive life.
